HYDROCARBON-BURNER.

T all whom it may concern:

` Be it known that I, ELMER WAL'I'ERB, a citizen of the UnitedStates, residing at Eldorado, in the county of Butler and State of Kansas, have invented a new and Improved Hydrocaibon-Burner, of which the following is a specification.

This invention has reference to that type of oils burners more particularly adapted for use on steam boilers and which are mounted on the boiler-for being projected into the combustionchamber of .the boiler with the torch or nozzle end positioned for directing the flame against the fire-wall of the said chamber. ff

Primarily, my invention seeks to provide a burner of the general type statediof a simple and economical construction, that has provision for being readily attached to and 20 for projecting it through the boiler and in are included for a thorough interniixing of the oil and air and drawing the mixed gas, under a forced steam jet feed, to the ignition or nose end of the burner.

With other objects in view that will hereinafter appear, my invention is an improved oil burner that embodies the peculiar feawhich means tures of construction and novel arrangement .c

-\of the parts to be hereinafter described in detail, specifically pointed out in the appended claims and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of-iny improved burner, so much of a boiler being shown asis necessary to illustrate a practical application of my invention.

Fig. 2 is a plan view of the burner, vthe boiler wall being shown in horizontal section.

Fig. 3 is a perspective view of a burner constructed in accordance with my invention.

Fig. Z1 is a transverse section thereof -on the line /-4 on Fig. 2.

Fig. 5 is a detail perspective View that shows the outer or tubular body with its gas and oil infeed lateral.

Fig. 6 is a perspective view of the'insde or steam jet pipe. My'improved construction of burner embodies a main or body portion 2 that includes a tubular member 1, one end of which terminates in a tapered or restricted portionl 2, the purpose of which will. presently appear and which merges with a forwardly extending nozzle 3 of uniform diameter and Specification of Letters Patent. l

which terminates in a tapering nose or ejetor end 4:.

At the other end, the body 1 is internally threaded, as 'at l5, to receive the externally threaded portion 6 of an injector pipe 7 that projects within the tapered end of the body or casing 1, as is clearly shown in Fig. l.

In the drawings, the several parts, as shown, are proportioned as follows: v

rlhe steam feed or ejector pipe extends six nearly the diameter of the outer or tubularbody 1, the fuel (mixed air-and gas),is drawn along a restricted passage and in contact with a large surface presented by the steam pipe and, by, reason thereof, the

vaporization of the fuel is much facilitated,

since lby heating the burner nozzle internally through radiation from the steam pipe, as 1t is externally heated in the boiler firechamber, the fuel vaporization is maintained under a uniform and perfect condition.

The outer 'end 8 of theejector -pipe is threaded for connection with one of the threaded tubes 9 of a T-coupling, the other end of which is normally closed by a screw plug 10.

11 designates a steam feed pipe that/connects with the T-coupling, as shown.

The burner body 1 is cast with tubular laterals 12-13 and to provide for connectin the air and gas and.' oil feed pipes-to eit er side of the burner, the latter has'a set of oil and gas laterals, at each side, as

shown, it being understood that, when the laterals`12-j13,atone side are being used, the laterals, at the other side, are closed by screw plugs 111-14.

In practice the oil inlet 12 is of larger diameter than that of the oil inlet, the two diameters in the form of my burner shown being one and one-fourth inches for the air Vinlet and one inch for the oil inlet.

1n the practical application of my burner, an openin of the diameter of the nozzle is made in t e boiler wall and at such point that the {ia'me from' the burner is ejected against the fire-wall 16 of the {ire-chamber 17 itbeing understood that a substantially tight connection of the burner with the body wall-is provided for by forcing the tapered portion of the burner into and upsetting 'the wall opening 18, as best shown in Fig. 1.

ibo

From the foregoing description taken in connection With the drawings, the complete construction, the advantages and the manner of the application of my invention will be readily apparent to those skilled 1n the art to Which my said invention relates.

What I claim is:

1. A burner of the type stated comprising a tubular body internally threaded at one end and Whose other end terminates in an ejeoting nozzle, a pair of laterals that communicate With the tubular body, means for connecting said laterals With air and gas feed pipes, a steam nozzle that includes an externally threaded hub portion for threading into the threaded end of the tubular body and a tapering ejecting nose that extends into the nozzle end of the tubular casing, the said hub portion of the steam nozzle having an outwardly projected extension adapted to receive union coupling for connecting the nozzle With a steam feed plpe.

2, A burner of the type stated comprisingy a tubular body internally threaded at one end and Whose other end terminates in an ejecting nozzle, pairs of oppositely projected tubular laterals that communicate with the tubular body, means for connecting adjacent pairs of the said laterals With air -and gas feed pipes, a steam nozzle that includes an externally threaded hub portion for threading into the threaded end of the tubular body and a tapering ejecting end that extends into the nozzle end of the tubular casing, the said hub portion of the steam nozzle including an outwardly projected tubularl extension threaded to receive a union coupling for connecting the nozzle With a steam feed pipe. v,
